-(-21) = -21 true or false

Answer:

42

Step-by-step explanation:

Graph all the points and then measure their lengths. Use Pythagorean Theorem for slanted sides. Picture explains everything. Sorry if my graph is a little messy, but you get the idea.

The correct choices would be scatter plots, line graphs, bar graphs option second, third, and fifth are correct.

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both the co-ordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

We have:

The chart or graph always use axes both labeled with quantitative values and show individual points of data.

Each point matches with one value on the x-axis and one value on the y-axis.

The chart or graph would be scatter plots, line graphs, bar graphs.

Thus, the correct choices would be scatter plots, line graphs, bar graphs.

Answer:

11

Step-by-step explanation:

For this problem, we simply need to apply the distance formula:

distance = sqrt[ (y2 - y1)^2 + (x2 - x1) ]

distance = sqrt[ (10 - 0)^2 + (4 - 0)^2 ]

distance = sqrt[ (10)^2 + (4)^2 ]

distance = sqrt[ 100 + 16]

distance = sqrt [ 116 ]

distance ~= 10.77

The approximate distance rounded to a whole number is 11.

Cheers.

Answer:

10.44 units (nearest hundredth)

Step-by-step explanation:

Distance between 2 points

[tex] = \sqrt{(y1 - y2)^{2} + {(x1 - x2)}^{2} } [/tex]

Distance between F and G

[tex] = \sqrt{(3 - ( - 7))^{2} + (5 - 2)^{2} } \\ = \sqrt{ {(3 + 7)}^{2} + {3}^{2} } \\ = \sqrt{ {10}^{2} + 9 } \\ = \sqrt{109} \\ = 10.44 \: units \\ (nearest \: hundredth)[/tex]

Answer: 11/74

Step-by-step explanation:

We have to think about what number can be divided from both 33 and 222. 33’s factors are 11 and 3. 222’s are 3, 6, 74, 37, and probably more. The only one the two numbered have in common is 3. So, divide north the numbers toe and denominator by 3 to get 11/74.

Answer:b=573

Step-by-step explanation:

xy = -2

(-3)(2/3) = -2

-2 = -2 TRUE

x + 3y = -1

-3 + 3(2/3) = -1

-3 + 2 = -1

-1 = -1 TRUE

x + z = 4

-3 + z = 4

z = 7 NEITHER

9y = -2x

9(2/3) = -2(-3)

6 = 6 TRUE

y/x = -2

(2/3)/(-3) = -2

-0.22... = -2 FALSE

-2/x / y = -1

-2/-3 / 2/3 = -1

2/3 / 2/3 = -1

1 = -1 FALSE

Best of Luck!

Answer:

A. xy = -2 - true

B. x + 3y = -1 - false doesn't equal -1 it equals -2

C. x + z = 4 - neither because z

D. 9y = -2x - false because it equals  -6

E. y/x = -2 - false because it equals -.2222222

F. -2/x / y = -1  - false it equals positive 1

Answer:

24 cm²

Step-by-step explanation:

Volume of a prism is equal to the area of the base times the height of the prism.

V = Ah

The volume is 120 cm³, and the height is 5 cm.  Therefore, the area of the base is:

120 cm³ = A (5 cm)

A = 24 cm²

Answer:

If you mean x2+y, then the answer would be 11.

Answer: x=5

Step-by-step explanation:

To solve for x, we want to use algebraic properties to isolate x.

-28+2x=-18        [add both sides by 28]

2x=10                 [divide both sides by 2]

x=5

Now, we know that x=5.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \text{x = 5}}}}}[/tex]

Step-by-step explanation:

[tex] \star{ \sf \: - 28 + 2x = - 18 }[/tex]

[tex] \tt{Step \: 1}[/tex] : Move 28 to right hand side and change it's sign

[tex] \hookrightarrow{ \sf{2x = - 18 + 28}}[/tex]

[tex] \tt{Step \:2}[/tex] : Subtract 18 from 28

The negative and positive integers are always subtracted but posses the sign of the bigger integer

[tex] \hookrightarrow{ \sf{2x = 10}}[/tex]

[tex] \tt{Step \: 3}[/tex] Divide both sides by 2

C. x = -7

2x + 23 = x + 16

x = -7

Answer:

The slope is 6. For the first line you could do y=6x+7, and the line parallel to that could be y= 6x+3

Step-by-step explanation:

For it to be parallel the slopes have to be the same and the y intercepts (b) have to be different. And I found the slope by doing y-y/x-x

plug in you numbers 19-7/5-3= 12/2 = 6

Answer:

since F is midpoint

DF= FE = 2x+6

DF +FE=DE

2x+6 + 2x+6 = 2x+36

4x + 12 = 2x+36

2x = 24

x=12

DE =2x+36 =2*12 + 36 = 60

Step-by-step explanation:

There are two conditions :

1) If data consumed is less than or equal to 2 GB.

2) if data consumed is more than 2 GB.

Change in 1st condition is constant i.e $50.

Now, charge in 2nd condition is given by :

[tex]C=15x+50[/tex]

So, money she have to pay in a month where she used ent over by x GB is :

[tex]C(x) = \$50\ , \ 0 \leq x \leq 2\\or\\C(x ) = \$\ (50+15x )\ ,\ x \geq 3[/tex]

Hence, this is the required solution.
